'''26/07/2017''' - in order to eliminate any endogeneity in the categorical variable "hub", a potential instrument is real estate taxes. If the real estate taxes are higher, there might be a higher demand for Hubs. Data on mortgage based real estate taxes was downloaded from the census data, using the American Communities Survey. A fixed effects IV regression shows that taxes don't perform as satisfactory IVs in this model.
'''31/07/2017''' - Estimated hazard rate using '''stcox''' in stata. Relevant do-file is '''hubs_load_data'''. It is located in Z>Hubs>2017>hubs_data.
'''1/08/2017''' - Explored stata routines for performing matching based on manually supplied scores. '''teffects''' only matches on automatically estimated probabilities. '''psmatch2''' has more scope of taking a manually estimated variable to match on.
'''2/07/2017''' - Estimated matched sample using Cox proportional hazard ratios. Relevant do-file is '''hubs_load_data'''. It is located in Z>Hubs>2017>hubs_data.
'''3/07/2017''' - After matching on hazard ratios, we need to first create a panel of T-C observations for diff in diff. More explanation on processing data for creating this panel is in [[Hubs Analysis 2017]].
